on account of weather. The beacon was first lit on March 15, 1950 and was controlled using forecasts from a meteorological agency located on the 26th floor. It was kept lit until 1973 when it was shut off to set an example during an energy crisis which also temporarily shut off the famed Citgo sign in Kenmore Square. The beacon was re-lit in 1983 and has continued to display the weather forecast ever since. In October 2004, the beacon flashed red and blue to commemorate the World Series victory of the Boston Red Sox. This was the first time the color scheme changed since the beacon was lit in 1950. A new line was added to the poem accordingly: Flashing Blue and Red, The Curse of the Bambino is dead! The beacon again flashed red and blue when the Red Sox won the 2007 World Series, as well as when they won the 2013 World Series. However, it did not flash red and blue the night they clinched the 2018 World Series.
